Usage Precautions
•Electrical interference
For safety considerations, the SampleTrak ST-224 has been designed to provide maximum protection
against the emission of electromagnetic radiation from inside the device, and protection from external
interference. However, equipment that is very susceptible to interference or that emits powerful
electromagnetic waves should not be placed near the SampleTrak ST-224, as the possibility of
interference cannot be ruled out entirely.
With any type of digital control device, the SampleTrak ST-224 included, electromagnetic interference
can cause malfunctioning and can corrupt or destroy data. Care should be taken to minimize the risk of
damage.
•Cleaning
Use a soft, dry cloth to clean the SampleTrak ST-224. If necessary, slightly moisten the cloth. Do not
use abrasive cleanser, wax, or solvents (such as paint thinner or cleaning alcohol), since these may dull
the finish or damage the surface.
Please keep this manual in a convenient place for future reference.

CONTENTS
Thank you for selecting the ZOOM SampleTrak ST-224 (hereafter simply called
the "ST-224"). The ST-224 is a sampler with the following features:
• Versatile sampler settings
The sampler section allows selection of three sound quality grades and stereo/mono
switching. Whether you want Hi-Fi for best sound or Lo-Fi for long recording time, the
choice is yours. Sampled waveforms can be stored in the internal backup memory or
on external data cards (option).
• Pad play feels like a rhythm machine
Sampled sounds are assigned to eight pads (x three banks) which can be played
with a simple tapping motion. Playback start and end position can be selected for each
pad, and parameters such as level, tuning, and panning can be easily adjusted.
• Sequencer stores 8 songs, PLAYLIST allows DJ use
An internal sequencer lets you memorize a pad playing session to create eight
original songs. The songs can then be assigned to pads 1 - 8 for real-time playing
(PLAYLIST).
• Useful special effects
The ST-224 also incorporates 22 powerful sound effects. A mixer function allows you
to assign an effect to one or more specific pads. Knobs and rotary controls on the panel
can be used to vary effect parameters in real time.
• Auto sync function-great for creating rhythm tracks
The beats per minute (BPM) of a sample assigned to a pad can be matched to the BPM
of one selected sample. Changing the length of a sample is possible without
changing pitch. This allows you for example to easily adjust the tempo of a drum loop
and bass pattern sampled from a CD.
• Sophisticated resampling feature
The ST-224 is the first unit in this price class to offer resampling. Phrases with
effects played with the pads or by the internal sequencer can be sampled again in the
digital domain.
• Built in presets and demo song
A number of built-in presets programmed at the factory lets you use the ST-224
right away. The unit also contains an impressive demo song making full use of the
various features.
Please take the time to read this manual carefully, so as to get the most out of your
ST-224 and to ensure optimum performance and reliability.
Except for special cases such as personal use, unauthorized sampling of material from copyrighted
sources (including but not limited to CDs, records, tapes, video clips, broadcast material) is
prohibited.

Press the [PLAY/STOP] key.
The sampled sound is played back, letting
you check the result of the process.
When wishing to redo the
sampling, press the [ERASE] key
to erase the sample (
➔
p. 36), and
then perform steps - again.
If the start or end of the sample is cut off, or
if it sounds distorted, you should redo the
sampling. If there is a blank period before or
after the sample, this can be removed later
and repeated sampling is not necessary
(

p. 29).
Press the [PAD ASSIGN]
key again.
Press one of the [BANK 1] -
[BANK 3] keys and then one of
the pads 1 - 8 to select the pad to
which you want to assign the
sample.
Press the [PAD ASSIGN] key twice.
The pad assignment is complete. Whenever
you hit the pad selected in step , the sound
of the sample will be heard.

This section explains the basic configuration of the ST- 224 as well as some important terms used in this
manual.
The illustration below shows the basic configuration of the ST-224. As can be seen from the chart, the ST-224
is made up of three main sections.
• Sampler
Samples the audio signal and performs playback using the pads and sequencer.
• Sequencer
Stores data about pad operation to enable automatic sampler playback.
• Effects
Allows alteration of the sampler signal in various ways.
The analog signal supplied via the [INPUT R] and [INPUT L/MONO] jacks is converted into digital form by
the A/D converter and the resulting waveform data are stored in the memory of the sampler section (main
memory).
Sampled and stored sounds can be played back in various ways, for example by hitting the pads on the unit, by
the internal sequencer, or under control of an external sequencer connected via the [MIDI IN] jack. The
maximum number of samples that can be played simultaneously is 8 mono samples or 4 stereo samples.
The sound of the samples played by the pads or sequencer can be altered if desired by the effects section, and
then appears at the [OUTPUT R] and [OUTPUT L/MONO] jacks. It is also possible to return this signal to the
sampling section and sample it again (resampling).
In the ST-224, a waveform that has been sampled in one sampling process is called a "sample". Each sample
automatically receives a number and is stored in the main memory. The ST-224 can store a maximum of 32
samples, depending on the size of each sample.
After sampling, the entire sample or a part of it can be assigned to one of the pads 1 - 8 on the front panel, for

playback by hitting the pad. For example, when sampling a drum pattern, a single drum sound or the entire
pattern can be assigned to a pad.
A combination of all settings for pads 1 - 8 is called a "bank". The ST-224 has three banks which are selected
with the [BANK 1] - [BANK 3] keys. In effect, the ST-224 therefore gives the user access to a total of 24 pads.
A pad to which a sample has been assigned has various playback parameters which can be set individually.
These parameters include playback start and stop position, level, tuning, and panning.
Note that changing these parameters does not affect the original sample. Assigning one sample to several pads
and setting these to different parameters result in different sound, but the original sample does not change or
become a new sample.
The [SOURCE] pad on the front panel is a special pad that allows using an
external input signal as sound source. It is not used for playing internal samples.

Introducing the ST-224
The following three types of memory are used in the ST- 224.
• Main memory
Volatile memory whose contents are lost when the ST-224 is turned off. Temporarily holds waveform data, pad
parameter setting data, and song data for the internal sequencer.
• Backup memory
Nonvolatile memory whose contents are retained also when the ST-224 is turned off. Serves for
permanently storing the entire contents of the main memory (bulk data). Only one set of bulk data can be stored
in the backup memory.
• Data card (SM04)
External storage media inserted in the [DATA CARD] slot on the rear panel of the unit. Like the backup memory,
it serves for storing bulk data, but it can hold more than one bulk data set (as many as the card capacity allows).
When the store target is a data card, up to 99 sets of bulk data can be stored.
When sampling or song recording is performed with the ST- 224, the waveform data and song data are
temporarily stored in the main memory. During pad play and song playback, the ST-224 will read data directly
from the main memory.
If the contents of the main memory are not saved to internal backup memory or to an external data card
(SM04), they will be lost when the unit is turned off. To prevent losing important data, be sure to save them
before turning the unit off, or more often if there is a possibility of power interruptions. Bulk data saved in
backup memory are automatically read into the main memory the next time the unit is turned on. (This means
that the unit returns to the same condition that was active before the power was switched off.) It is also possible
to manually load data from backup memory or data cards into the main memory.

WAV file/AIFF file
BPM (beats per minute) is a tempo unit that indicates the number of quarter notes per minute. For example, a
piece where a quarter note is 0.5 seconds long will have a BPM figure of 120, whereas a piece where a quarter
note is 1 seconds long will have a BPM figure of 60.
The ST-224 handles three types of BPM, which can be set individually.
• Song BPM
Indicates the tempo of a stored song. This value is stored separately for each song.
• Pad BPM
Indicates the playback time of a pad. The ST-224 considers the playback time of a sample assigned to a pad to
be four beats (quarter note x 4) and automatically calculates the BPM for the pad. This serves mainly for
synchronizing the tempo of several pads (Auto Sync feature). When parameters such as the sample start
point and end point, tuning etc. are changed, the pad BPM also is adjusted automatically.
•
Effect BPM
Serves for synchronizing the parameters of certain effects (delay time, flanger modulation speed, etc.) to a given
tempo. The synchronized parameter depends on the effect type (some effect types do not have a parameter that
can be synchronized).
The value of Effect BPM is same as Song BPM unless edited.
For each type of BPM, the setting range is 40 - 250.

Let's Try Out Sampling
This section explains how to use the [RECORD] key to manually specify the start and end point of the
sampling process. Manual sampling is convenient for example for quickly sampling a desired rhythm or bass
pattern while listening to a CD.
Except for special cases such as personal use, unauthorized sampling of material from copyrighted sources
(including but not limited to CDs, records, tapes, video clips, broadcast material) is prohibited.
• In the factory default condition, the ST-224 will read the preset sample sources from
backup memory into the main memory. Also in this condition, it is possible to sample a new
source and store the result in a free area of the main memory, but for maximum recording
length, you should first erase some or all preset samples from the main memory (
➔
p. 36).
• The sampled waveform is temporarily stored in the main memory, but it will be lost if the unit
is turned off without first transferring the waveform data to the internal backup memory or
external data cards. (The next time the unit is turned on, the contents of the backup
memory will be read into the main memory.) Be sure to store important sample data (
➔
p. 59).
NOTE
The ST-224 goes into the sampling standby mode, and the LED of
the [RECORD] key flashes. A number for the new sample is shown on
the display.
The currently selected grade appears on the display. You can change
the grade between three settings by holding down the [GRADE] key
and using the [-] and [+] keys.
